TNS mode
TNS mode. The operational environment in which TNS instructions execute by inline 
interpretation. See also TNS accelerated mode and TNS/R native mode.
TNS/E native mode. The primary execution environment on a TNS/E system, in which 
native-compiled Intel® Itanium® object code executes, following TNS/E native-mode 
compiler conventions for data locations, addressing, stack frames, registers, and call 
linkage. Compare to TNS interpreted mode and TNS accelerated mode. See also 
TNS/R native mode.
TNS/E system. HP computers that support the NonStop operating system and are based 
on Explicitly Parallel Instruction Computing (EPIC) technology.
TNS/R native mode. The primary execution environment on a TNS/R system, in which 
native-compiled MIPS object code executes, following TNS/R native-mode compiler 
conventions for data locations, addressing, stack frames, registers, and call linkage. 
Compare to TNS interpreted mode and TNS accelerated mode. See also TNS/E native 
mode.
trap. A software interrupt that provides a way of handling certain events, such as detection 
of a hardware (or software) fault, a timer expiration, or a lack of system resources. A 
trap is often an indication of a run-time event that requires immediate attention; most 
such events preclude continuing the interrupted instruction stream. Traps are 
generated for TNS Guardian processes. (TNS/R native Guardian processes and all 
OSS processes receive signals instead.) An Instruction Failure trap indicates that an 
instruction could not executed because the instruction or its data were invalid. 
Compare to signal.
